Urban Computing

Urban Computing: “The integration of computing, sensing, and actuation technologies into everyday urban settings and lifestyles.” [Kindberg et al.]

Main characteristics of urban settings Complex ownership More dynamic and dense (participants and applications)

Important aspects to consider together Spatial semantics Social behaviors & relations Temporal contexts

IEEE Pervasive ComputingJuly-September 2007


New Challenges

User-centricity On-demand application composition (mash-up) Connecting users’ high-level needs to the services,

devices, and connections Considering essential human factors such as usabil-

ity and cognitive resources while proving software services

Dynamism Making applications reconfigurable with different

services and devices under different environments Memorizing and reusing useful applications for cer-

tain situations and environments Making applications evolvable based on changing

user requirements and situations

New SE Paradigm

March 2013


Main Approaches

User-oriented Service Computing Enable high-level software design (in multiple ab-

stractions) with primarily considering user tasks Support iterative and gradual development Improve reusability Enable application adaptability

Semantic Web Enabled Software Engi-neering Improve correctness and context awareness Improve interoperability

End-user Software Engineering Support semi-automatic composition Enable visual programming (mash-ups)

Semantic-Cloud-based Multimedia Se-mantic Annotation

Makes it easier for users to add semantic annota-tions to multimedia con-tents

Uses semantic clouds as the primary interface for semantic annotation

Generates efficient se-mantic clouds from Linked Data

Users can easily resolve semantic ambiguity and choose the most appro-priate semantic cloud
